Chapter 3: Board Component Descriptions
The USB3320 ULPI U116 transceiver circuit (see Figure 3-4) has a Micrel MIC2544 high-side
programmable current limit switch (U121). This switch has an open-drain output fault flag
on pin 2, which turns on LED DS51 if over current or thermal shutdown conditions are
detected. DS51 is located in the U116 circuit area near pushbutton SW4 (Figure 2-1, callout
20).
